Olivia Wilde is Lucky magazine’s gorgeous May cover girl, which is perfect timing since she’s giving birth to her baby boy that same month!

In the issue, the 30-year-old actress talks all about what it’s like to be a first-time pregnant lady, and you’ll never believe what she tried to hide!

Her entire pregnancy!

But she just couldn’t because it made her feel so awesome! Olivia explained:

"I just thought, oh I'm going to hide this forever. But I ended up getting kind of excited to show the bump, as a badge of pride, like, 'I'm a woman! Look at me making a human! I am a goddess!’ Pregnancy brings you into this sort of commune—you feel connected to women in a way that you never have. He's moving around in there and no one else can tell—it's a little secret friendship.”

Awww! That’s the cutest description EVER!

And Miz Wilde is enjoying some of the benefits of pregnancy a lot, like having bigger boobies:

"I'm like, double D, hello! I’ve never been in this section of the bra store! I've been flat-chested my whole life, so it's a wonderful new world."

Ha! Between having her for a mom, and Jason Sudeikis for a dad, we’re sure this baby is just going to be HIGHlarious!
